需要评估土地使用的变化，以满足未来的需要。其中之一是努力减轻自然灾害。本文的研究目标是分析2001-2017年期间土地利用/土地覆被变化与河流流量之间的相关性。本研究位于东爪哇最大的流域Brantas流域。面积约11，988平方公里。有2400万人居住在这一地区，这是国家战略流域之一。SHETRAN是基于物理分布的建模。考虑到空间方面，水文和气候数据使SHETRAN是一个综合性的模式。所使用的方法是将数字高程模型的输入数据、蒸发率、降雨量数据、土地利用土地覆盖数据和使用英国系统分类的土壤特性联合收割机组合。结果得出，对于土地利用，变化最大的是草地面积增加了80.49%，森林面积增加了22.37%。至于河流流量，建模结果表明，上游河流流量范围为6-30，下游河流流量范围为1200-2200米3/秒。
Changes in land use need to be assessed for future needs. One of them is in efforts to mitigate natural disasters. This research goal is analyzed the correlation between changes in land use land cover on the discharge in the river, in the range between 2001–2017. This research located at Brantas watershed, which is the largest watershed in East Java. It has an area of approximately 11,988 km2. There are 24 million people who occupy this area and this is one of the national strategic watersheds. SHETRAN is modeling that is based on physical distribution. Reviewing spatial aspects, hydrological and climate data makes SHETRAN is comprehensive model. The method used is to combine input data of the digital elevation model, evaporation rate, rainfall data, land use land cover data, and soil properties classified using the British system. The results obtained for land use, the biggest change is for the grass area which increased by 80.49%, the forest area increased by 22.37%. As for river discharge, modeling results indicate that river flow rates upstream range 6–30 compare to downstream is between 1200–2200 meters3/second.
