Climatic Water Balance and Groundwater Recharge in Abu-Jir Village, Al- Anbar Governorate, Western Iraq


The study area is located in Al-Anbar Governorate, western Iraq. The climaticdata were collected from Al-Ramadi Meteorological Station for the period 1990 to2020 and used to assess the climatic condition of the study area. The total annualrainfall, relative humidity, monthly average temperature, evaporation, wind speedand sunshine duration are 108 mm, 52.7 %, 22.6˚C, 2814.3 mm, 2.2 m/s and 8.8h/day, respectively. The climate of the study area is described as an arid to sub aridand relatively hot in summer and cold with low rain in winter. During the data used,the highest potential evapotranspiration was 217.1 mm in July, while the lowestvalue was 10.7 mm in January, with a total amount of 1170.07 mm. The highest andlowest corrected evapotranspiration becomes 264.2 mm in July and 9.4 mm inJanuary, with 1310.3 mm. water Surplus (WS) is 2.1mm, 10.71mm, and 5.65mm inDecember, January and February, respectively. The WS was 18.46mm, forming17.09 % of the total annual rainfall. The groundwater recharge (18.46 mm) with arate of 17.09% represents the recharge from the total rainfall zero surface runoff. Ithas been found that the low amount of rain and sandy soil are among the mostimportant factors causing the absence of surface runoff.
