Six hectares Chandra Kirana Regency comprises 223 units. It needs a proper 1854 m drainage system completed with run-off water tanks to avoid it from floods.The objective of the study is to design the drainage system and run-off water tanks able to control the rainwater completed with the implementation cost and time.Site plan, topographic map, and rainfall data were needed to design. Rainfall data from 3 nearby stations: Singosari, Jabung, and Blimbing from 1991-2010 were analyzed to find out the maximum rainfall data and average rainfall regions using Mean Algebra. Log Pearson III was employed to obtain the rainfall, Mononobe method was for the rainfall intensity.The addition of rain water to waste water results in 0,00004 m/sec. cumulative discharge. Based on the result, and 0,5 m diameter culvert rings are designed. 1 m diameter and 2 m deep run-off water tank is of precast concrete. 93 work days implementation time at IDR  1.061.479.450,00.Keywords: design, drainage system, proper, rainwater, water tank

The purpose of this high intensity rainfall analysis is quantization of a rainfall phenomenon. Hereafter the statistical methods are presented but only the basis of these, also the application to some real rainfall data and finally the differences among those methods are discussed. The most important components of a calculation by different methods are presented by an example. The complex information concerning small duration high intensity rainfall is useful for both hydrologist and design engineer and also necessary for urban run-off calculations and drainage system analysis.

Moving Points

Landslide can be defined as the mass movement of sloping slopes under the influence of mass gravity and its stimuli such as earthquakes, floods and flood plains. This phenomenon is one of the natural hazards that every year causes a lot of financial and financial losses in mountainous, rain-fed and seismic areas. Detection of time and the magnitude of landslides are necessary to understand the causes of landslide and to warn potential hazards. In this research, the amount of landslide displacement in Kermanshah province was evaluated by the characteristics of rainfall. To this end, a network of fixed points in and out of the slipping mass of 20 points was created to monitor the amount of displacement on different slip load users and the amount of displacement of each point in 5 time intervals using the Global Positioning System for two-dimensional GPS measurement. The results of the 511-day follow-up showed that the total horizontal displacement of the moving points in the 5 intervals measured at 1658 mm has a monthly displacement rate of 112 mm. Also, the total vertical displacement of moving points at the same time is 899 mm, with a monthly movement rate of 71 mm. Then, precipitation variances such as rainfall, rainfall, precipitation duration, maximum rainfall intensity in the intervals of 10, 20, 30 and 60 minutes and the average rainfall intensity were calculated and extracted for each of the 5 time periods. The drawing of the vectors of points on the topographic map of the area indicated that the direction of mass movement is in the direction of elevation gradient of the region. The results showed that only the precipitation severity with the landslide had a good correlation. The landslide movement had the highest correlation with average rainfall intensity (R = 0.85) and with maximum 30 minutes rainfall (R = 0.67), respectively, and other rainfall characteristics like amount, duration, and type of rainfall had not significantly correlated with movement of landslides.

Runoff Model

The present research develops a systematic application of a selected family of 11 well-known design storms, all of them obtained from the same rainfall data sample. Some of them are fully consistent with the intensity–duration–frequency (IDF) curves, while others are built according to typical observed patterns in the historical rainfall series. The employed data series consists on a high-resolution rainfall time series in Valencia (Spain), covering the period from 1990 to 2012. The goal of the research is the systematic comparison of these design storms, paying special attention to some relevant quantitative properties, as the maximum rainfall intensity, the total cumulative rainfall depth or the temporal pattern characterising the synthetic storm. For comparison purposes, storm duration was set to 1 hour and return period equal to 25 years in all cases. The comparison is enhanced by using each of the design storms as rainfall input to a calibrated urban hydrology rainfall–runoff model, yielding to a family of hydrographs for a given neighbourhood of the city of Valencia (Spain). The discussion and conclusions derived from the present research refer to both, the comparison between design storms and the comparison of resulting hydrographs after the application of the mentioned rainfall–runoff model. Seven of the tested design storms yielded to similar overall performance, showing negligible differences in practice. Among them, only Average Variability Method (AVM) and Two Parameter Gamma function (G2P) incorporate in their definition a temporal pattern inferred from empirical patterns identified in the historical rainfall data used herein. The remaining four design storms lead to more significant discrepancies attending both to the rainfall itself and to the resulting hydrograph. Such differences are ~8% concerning estimated discharges.

Lombok International Airport is the premier second-class airport located in Tanak Awu, Pujut, Lombok Tengah, Nusa Tenggara Barat which functions to serve transportation services. Lombok International Airport has runway, apron, and two taxiways along with its drainage. The drainage system is needed to prevent puddles of rainwater in the runway, taxiway and apron that can obstruct the aircraft movement. However, looking at the existing condition of the Lombok International Airport’s trunk, it is necessary to conduct research about trunk reconstruction for the next ten years’ time.The research is begun by collecting data such as existing elevation, existing dimension, slope of existing trunk and rainfall data for the last five years. From these data, an analysis of the rainfall plan is carried out using gumbel distribution method. Furthermore, from the results of the analysis, it is obtained the daily maximum rainfall which is used to know the rainwater runoff debit. Re-planning the dimensions of Lombok International Airport’s trunk is carried out to accommodate rainwater runoff debit for the next ten years since the existing dimensions of the existing trunk cannot accommodate rainwater runoff debit for the next ten years. Therefore, it was obtained the design plan for the reconstruction of each segment with a length of 1,2 meters, width of 1,84 meters and height of 1,77 meters. Re-planning the dimensions of the trunk is in precast concrete.

The scarcity of safe drinking water is one of the problems faced by the majority of cities in the world. Kirkuk city is one of these cities, which suffer from a shortage of drinking water. People have adopted the use of different rooftop tanks to overcome this problem. This research focuses on studying the effect of storage time on the five main characteristics of drinking water, which include, acid index (pH), electrical conductivity (EC), total suspended solids (TSS), total dissolved solids (TDS), and turbidity (Tr). Three types of tanks were used predominantly (galvanized metal, plastic, and aluminum tanks). By analyzing the results, the characteristics of three samples of municipal source water obtained. Three samples were taken from each tank at different periods (4, 8, and 12 days). The results showed that the storage time affected the characteristics of drinking water. These characteristics differed from one tank to another. Metal tanks showed an increase in total dissolved solids, due to the evaporation process, even as plastic and aluminum tanks showed an increase in pH. The properties of all storage water tanks changed with times, but overall, the results were within the Iraqi limitation for drinking water. It was not easy to only depend on the results of this study to believe that any one type of water tank was better than the other, as the values of most of the variables studied had varied from one type to other. However, many studies have indicated a number of health risks, and most significantly with regard to plastic tanks, which are said to contain dangerous organic compounds that can be transferred to water. Metal tanks can cause zinc leakage, caused by a number of environmental factors at high levels. Aluminum tanks also can have an effect on the water in tanks.
