Method Of Design

On-site stormwater detention is widely used in Australia as a means of controlling the increased storm discharges from urban consolidation projects. However, unless the maximum permissible site discharge is correctly determined, the local piped drainage system may be overloaded. This paper presents a generic methodology that integrates detention storage behaviour with drainage design theory in such a manner as to protect the entire length of the downstream drainage system. Its generic nature facilitates its universal application to all systems, protecting these valuable community assets throughout their service lives.

A problem for drainage systems managers is the increase in extreme rain events that are increasing in various parts of the world. Their occurrence produces hydraulic overload in the drainage system and consequently floods. Adapting the existing infrastructure to be able to receive extreme rains without generating consequences for cities’ inhabitants has become a necessity. This research shows a new way to improve drainage systems with minimal investment costs, using for this purpose a novel methodology that considers the inclusion of hydraulic control elements in the network, the installation of storm tanks and the replacement of pipes. The presented methodology uses the Storm Water Management Model for the hydraulic analysis of the network and a modified Genetic Algorithm to optimize the network. In this algorithm, called the Pseudo-Genetic Algorithm, the coding of the chromosomes is integral and has been used in previous studies of hydraulic optimization. This work evaluates the cost of the required infrastructure and the damage caused by floods to find the optimal solution. The main conclusion of this study is that the inclusion of hydraulic controls can reduce the cost of network rehabilitation and decrease flood levels.

In industrial areas or densely populated settlements, generally found channels that function besides to drain rainwater as well as to discharge domestic wastewater or dirty water from households. Drainage systems are often the main problem in the occurrence of flooding. It is necessary to analyze how their performance and resistance to flooding in the District of Gandusari, Trenggalek Regency. For analysis of drainage system planning in flood prevention efforts, the authors used the Van-Breun and Mononobe calculation methods to determine the number of incoming water discharge, the ideal dimension of the channel to accommodate the inlet discharge channel, and calculate the cost budget plan (RAB) of the builder. From the analysis, results obtained a cumulative discharge of rainwater, and dirty water entering the drainage amounted to 0.4695 m3 / sec. From the calculation, the ideal dimensions of the drainage can be obtained to be able to accommodate rainwater runoff and dirty water discharge using square channels, where the 1.5 m channel height is all added to the water level of 0.2 m and 0.7 m in width 500 m. While the budget plan for the construction costs is Rp. 794,048,000.00 -Di daerah industri atau pemukiman padat penduduk umumnya ditemukan saluran yang berfungsi selain untuk mengalirkan air hujan juga sekaligus untuk pembuangan air limbah domestik ataupun air kotor dari rumah tangga.

Linear investments cause irreversible changes in the existing shape and way of using the land located alongside it. In the case of the construction of the highway, these lands are mostly located in rural areas and prior to construction, they were used mostly in agriculture. Losses resulting from such investments affect the natural environment and landscape. Along the impact zone wind conditions change, also exhaust emissions and noise increase. Investors try to avoid the design of wide protection zones of greenery, due to the cost of buying a larger area of land and they usually use it only when it is necessary. Severe ecological losses result from land degradation, disturbances in the drainage system and changes in water relations. Such investments also have a negative impact on the profitability of agricultural holdings, in particular organic farms. The market value of land adjacent to the motorway is also decreasing. Often, on both sides of the motorway there remain land with a small area, access to the ground is difficult or even impossible. In order to reduce the negative impact of linear investments on the spatial structure of agricultural areas, infrastructure integration is carried out. The implementation of consolidations related to the construction of motorways in Poland is not a common and frequent phenomenon, which lacks concrete plans and schemes of actions. The paper presents the objectives of consolidation in the area of the village of Szczepanow in the Lesser Poland Voivodeship.

Rheological analysis provides a good comprehension of the deformation and flow of substances under different stress conditions. The complex composition of the drilling fluid and the versatile functions makes rheological studies here indispensable as well as in other scientific fields like the food industry and material science. In spite of adding many high-quality additives to the drilling fluids, problems still occur, such as barite-sag, lost circulation, change of mud properties (particularly at high and very low temperature), solids transport. Others are often mentioned as reasons for increasing the cost of wells. The areas in which rheology plays an important role in drilling technology will be highlighted in this article. The reason, why the characterization with the Fann-viscometer alone is not enough for a detailed view on rheology will be focused on. In addition, measuring methods which are able to provide detailed information about gel strength, consistency, gel destruction, gel build up process and yield point have been investigated. A short overview of the basics of rheology is given. In this article, novel procedures will be shown on the basis of flow curve, hysteresis loops, amplitude sweep and 3-interval-thixotropy-test (3ITT). With these procedures, deeper knowledge about the drilling fluid system can be obtained. Implementing these procedures and considering their results in hydraulic calculation programs or taking them into account by the design of drilling fluids, can reduce costs and lead to safer drilling process in general.

The drainage system is used to guide the flow of water in the earth dams. Construction of drainage in the dam body to collect and direct the drainage formed in the dam body to keep the slope dry and prevent the increase of pore water pressure in the body. One of the main goals of the designers is to find the minimum factor of safety and, consequently, reduce the cost of construction. In this study, the Marvak dam is modeled with the actual characteristics of the materials in the Geostudio software, and with the change in the dimensions of the drain, the material and the slope of the dam body, the minimum Factor of safety of the dam is obtained. In order to predict the minimum Factor of safety, a two-layer neural network has been used. With the training of the neural network based on the data obtained from heterogeneous dams, a minimum Factor of safety has been extracted for optimization of drainage. Finally, it was determined that the internal friction angle of the body material and the slope of the dam have the greatest effect on the dam factor of safety.

An estimation of optimal design parameters of subsurface drainage system through monitoring of water table depths and drain discharges are expensive in terms of time and money. The simulation modeling is an effective tool for estimation of drainage design parameters at less cost and short time. In view to this, calibration of DRAINMOD model for prediction of water table depths and drain discharges were conducted by installing subsurface drainage system with 40 m drain spacing and 1.0 m drain depth at Agricultural Research Station, Kasbe Digraj, Dist. Sangli (Maharashtra) during 2012-13 to 2013-14. The field data on water table depth and drain discharge were used for calibration of DRAINMOD model. The input data files on climatic, soil, crop and drainage design system parameters were attached to DRAINMOD model and calibrated successfully. It is found that both observed and simulated water table depths and drain discharges showed a fluctuating trend and predicted both water table depths and drain discharges closely with the observed values during frequent rainy days and following the rainy days. The DRAINMOD model reliably predicted water table depths with a goodness of fit (R2 = 0.97), MAE (12.23 cm), RMSE (15.49 cm) and CRM (0.05); drain discharges with R2 of  0.93, MAE of 0.095 mm day-1, RMSE of 0.1876 mm day-1and CRM of 0.04. Thus, the calibrated DRAINMOD model can be used to simulate the water table depths and drain discharges in semi-arid climatic conditions of Maharashtra and in turn to estimate and evaluate drain spacing and depth.

ABSTRACT In Brazil, urbanization-dominated imperviousness is prevalent, increasing the incidence and magnitude of floods. An alternative to control this impact is an on-site runoff detention reservoir. The choice of reservoir adopted should ideally combine hydraulic/hydrological and structural/economic criteria, although there is a gap in the literature regarding this type of integrated analysis. In this article, a cost-efficiency analysis is conducted to select a reservoir to control the runoff captured by a roof (4,657 m2) using the Puls method for hydraulic dimensioning and based on technical standards for the design of concrete structures. The results indicate that a decrease of approximately 3% in the theoretically ideal efficiency (100%) of the reservoir provided a 36% drop in cost. Such an alternative is more likely to become attractive and economically viable, with virtually the same benefits to the downstream stormwater drainage system. The analysis of different alternatives induced a decision between the level of control of the reservoir output and the cost that emphasized different aspects, focusing on more than the minimization of the cost or the imposition of a pre-defined control level in an arbitrary way.
