التنبؤ عن غيض الماء و الإيصالية المائية للتربة في وسط السهل الرسوبي باستخدام تقانات الاستشعار عن بعد

Studies within the last two decades have pointed out the importance of remote sensing techniques to deduct soil properties.

These techniques showed promising results as a suitable alternative with lowest cost in compare with other methods used to measure soil characteristics (10).

The aim of this study is to test the relationship between landsat (ETM + sensor) data and infiltration rate and saturated hydraulic conductivity of soils with ten different selected soil units.

These soils which have variations in geomorphology and soil characteristics are located at the north of Kut city (Middle part of Iraq to the left of Tigris river).

Statistical Analyses were performed and statistical models were built up to predict the two soil characteristics using remote sensing techniques.

The results showed the statistically significance of the relations between the soil water infiltration rate values and the remote sensing data for the soil surface layer, with determination coefficient (R2) of 0.9 .

while the saturated hydraulic conductivity for the soil layer at depth 25-50 cm, showed weak correlation .These results demonstrate the weak relation between ETM + sensor data and soil data with depth .
