Spatial Variation of Temperature and Rainfall Trends in Kabul River Basin

Knowledge of temperature and rainfall periodicity is needed for urban and rural land-use and infrastructure planning, and their flood protection. In this study temperature and rainfall data from Climatic Research Unit Time Series version 4.03 (CRU TS4.03) was downloaded and inverse distance weighted (IDW) were made to analyze the temperature and precipitation variations in Kabul river basin (KRB). Interpolation maps were made using ArcMap 10.4.1. Analysis was done for period from 2004 to 2018. Annually for 15-year period, mean temperature variation can be noted as, upper part of the basin has minimum temperature of -1.2 °C while part of the study basin that lies in Pakistan has maximum temperature of 19 °C. Rainfall varies from 380 mm to 793 mm annually for 15-years. Due to increasing trend of both temperature and rainfall for KRB suitable methods should be applied for water management and flood risk reduction.
