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.

The Relationship

Aimed at the feature of expressway subgrade drainage facilities in typical red sandstone areas in Jiangxi province and based on the importance of the structure, damage conditions, service requirements and the current specification requirements related to various types of ditches, the designed repetition period of rainfall and proposed safety depth values for drainage facilities were put forward by considering reasonably the key design parameters to regional drainage facilities. The relationship between prerequisite of discharging sediment in ditches or conduits and minimum longitudinal gradient was discussed. Combined with the characteristics of red sandstone subgrade drainage with high requirements, the design elements of red sandstone area expressway subgrade drainage system were obtained, which can provide beneficial references for the subgrade drainage design in red sandstone areas.

With the rapid development of China's economy and the increasing levels of science, our country's high-rise building height and number of layers is also increasing. Especially in the 21st century, our country develop toward the height of high-rise buildings ever higher, more layers, better equipped, more complete, more advanced technology more economically rational. High-rise building has become a symbol of a modern metropolis. However, due to the high-rise buildings have many people, so relevant norms on its construction and drainage system design and fire safety, reliability and economic practicality of a higher requirement, this requires a high-rise building water supply and drainage system on the technical design more reasonable, economic budget cost savings at the same time to achieve its design function.

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.

Jakarta’s dense population has caused a disorder in the urban system by negatively impacting its streams. Therefore, this research aims to find out the urban district design criterias with rainwater harvesting system and how to implement them in residential areas of Kebon Melati, Tanah Abang. Data collecting techniques used in this research include literature studies, field observation, and interviews. The proposed solution to Jakarta’s rainwater problems is to design a district which incorporates the four potential urban design theory applications into it. The first theory is about land use related to storage and drainage system. The second theory is about vehicle circulation and pedestrian paths related to roadblock gaps and permeable materials. The third theory is about building mass and shape related to catchment area, conveyance, and green roof. The last theory is about open spaces related to water retention basins. The goal of this urban district design is to develop and decrease the speed of rainwater flow in Kebon Melati.

The main provisions of the methodology for calculating and designing a "green drainage system" of surface runoff from the road network of settlements that are not equipped with an underground drainage and treatment system are given. Requirements for the "green drainage system" of surface runoff from urban streets that are not equipped with an underground drainage system are formulated. The requirements include the treatment degree of surface runoff, filtration rate, comfort of the visual environment, safety and convenience for pedestrians and bicyclists, technologies of winter maintenance. The main pollutants of surface runoff for different categories of Russian streets are identified. The composition and depth of filtration media, its operating life, types of green plants are determined depending on the composition of pollutants, their typical concentrations, the collection area of surface runoff and the composition of native soils. Examples of the most effective design solutions for the "green drainage system" and treatment of surface runoff from the road network are given.

ABSTRACT The nasolacrimal drainage system begins development in the third fetal months from a cord of epithelium found between the maxillary and frontal nasal recesses. Canalization of this cord along its entire length leads to its communication with the inferior nasal meatus by the sixth fetal month. Failure of canalization is the most common cause of nasolacrimal drainage obstruction use of endoscopes in children is evolving, may it be endoscopic DCR or other congenital problems. In spite of the smaller anatomic dimensions posing a technical challenge, the endonasal endoscopic approach to nasolacrimal obstruction in children not only avoids a scar, it preserves the function of the lacrimal pump also.

Wetlands have a very important role for humans and the environment. The function of wetlands as a support for human life, among others, water sources, a variety of habitats for living things, controlling floods, and drought. One of the wetlands in the Kelik river, Ketapang Regency. This wetland has an area of 2600 ha. The land is now a conservation area, with cultivation rights. The existing problem, namely, the land is the residual combustion that occurred in 2015 and is always flooded with water and the need for an existing drainage system on the land. Land needs to be managed properly in water management. Efforts to manage conservation areas so as not to experience drought, which results in fires, which will threaten land conservations. Methods for dealing with drainage systems by utilizing existing ditches or drains. Drainage design using hydrological and hydraulic studies. The method used in determining the flood discharge plan is based on the need for drainage modulus and the area of the ArcGIS software aid sub-area. The results of the study indicate the need to improve the existing channel. Repair through efforts to deepen the trenches and hold widening or normalization. Also, the depth of the new channel is needed to make an automatic door so that the water can be grounded to maintain the availability of water in the ground.
