Abstract

Population growth is one of the causes of land-use change that can increase runoff. Tanggul watershed is one of the watersheds which often overflows during the rainy season. This study purpose to analyze the effect of land-use changes on runoff in Tanggul watershed using SWAT (Soil and Water Assessment Tool) model. To make sure the performance of SWAT model calibration and classified by the value of NSE and R2. The result of calibration included in a good category and validation included in a very good category. This study was modeling forest land-use change in 2004-2017 to determine the effect of land-use change on runoff. The result in this model of forest land-use change can increase runoff.

Abstract

The most often problem that is usually occurred in the field is damage of discharge measuring building. In Kesilir’s primary channel, they are crumpweir dan cipoletti measuring structure that have decreased in fuction. This research was conducted by analyzing the discharge obtained from field data collection, wet cross-section area (A), flow velocity (v) and peilscal height (h). Callibration analysis of discharge measuring building is carried out by differentiating between the equation resulting from the graph using power function. The research result in the measurement differences of the upstream and downstream of the channel at two locations. The callibration coefficient of the crumpweir is 0.39 and the cipolleti is 0.72 respectvely.
