Urban growth is one of the major causes of flooding in urban areas. This affects the runoff coefficients, which is among the most important factors that affect the design of storm water drainage systems. Changing the runoff coefficient will affect the design parameters of the drainage network, including outfall discharge, velocity, lag time and cost of construction. This study aims to assess the effect of changing the runoff coefficient due to urban growth on the design of a storm water drainage system. The hydrological models Hyfran, StormCAD and GIS are used to analyze different runoff coefficients. This study examines three zones in Dammam in the Kingdom of Saudi Arabia (KSA). The data developed from the models for the current case studies are used to develop an empirical equation to predict the max discharge for other catchments. The discharge is a function of the return period, runoff coefficient, drainage density, longest path, rainfall intensity and catchment area. To validate the developed equation, we use it to estimate the discharge in a real case study in South Korea. A comparison between the measured discharge and estimated discharge shows that the empirical equation is capable of predicting the maximum discharge for different catchments with high accuracy. Then, the validation of the models is carried out to determine the effect of the runoff coefficient on the design of a storm water drainage system in a case study in KSA. The results show that an increasing runoff coefficient due to urban growth increases the outfall discharge and velocity of storm water drainage systems, as well as affecting the cost of construction and decreasing the lag time. The cost increases by two to three times with increasing urbanization. This study provides a new perspective on the hydrologic impact of urban growth on the design of storm water drainage systems, which are essential for flood management. Moreover, the relationship between urban growth and the cost of storm drainage networks is explored, which could help decision makers to make appropriate judgements.

Abstract This paper aims to analyze the variability of the levels of surface and ground water in the Ochożanka basin. The depth at which the ground water table occurred was studied with reference to the adopted land drainage standards. The studies were carried out in 2009/2010–2014/2015 for natural and regulated water outflows. The analysis of annual total precipitation in the analyzed period some years were very wet (2009/2010 and 2013/2014), some of them were wet (2010/2011, 2012/2013), one year was dry (2014/2015) and one year was normal (2011/2012). The six-year average seasonal precipitation amounted to 593 mm, which was 66 mm higher than average precipitation recorded in 30 years. Under regulated outflow conditions the level of water in the river ranged from 55 to 77 cm. The level of water under natural outflow ranged from 18 to 49 cm. In the area with regulated outflow the average ground water level was 47 cm. In the remaining area of drainage system ground water level was 67 cm. Also, the dynamics of variance in the water level under natural outflow conditions was clearly higher.
