K T Model for Daily Natural Runoff Analysis by Using Air Temperature and a Storage Constant K The Proposal and the Application for Nagara River

Abstract

KT Model is a daily natural runoff model. I propose it and show it's good results in NAGARAGAW so Acalled natural river. It's very simple model with only one constant K relating to basin recharge and recession in low-water. The daily natural runoff is dtermined by the daily precipitaion and the daily air temperature. Loss in natural runoff is evaporation. It refers to air temperature. In this basin I obtained K=30 and a relation of evaporation and air temperature E=1.03+0.083T.
