1. High frequency rainfall data disaggregation with a random cascade model : Identifying regional differences in hyetographs in Sweden
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The field of urban hydrology is in need of high temporal resolution data series in order to effectively model and analyse existing and future trends in extreme precipitation. When high resolution data sets are, for any number of reasons, not available for a given location, the technique of disaggregation using a random cascade model can be applied. READ MORE

2. Modeling hydrometeorological extremes in Alpine catchments
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Uncertainties with a modeling framework consisting of a weather generator, two precipitation disaggregation models and the hydrological HBV model was assessed with respect to hydrometeorological extremes in Tyrol, Austria. Extreme precipitation events are expected to increase in intensity and frequency in the Alps during a warmer climate. READ MORE

3. Exploring the spatial relationship between NDVI and rainfall in the semi-arid Sahel with geographically weighted regression
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The Normalized Vegetation Difference Index (NDVI) is frequently used as a surrogate for vegetation properties and is often correlated with climatic variables such as rainfall. However, studies have shown that conventional regression models used to study the spatial relationship between NDVI and rainfall are often plagued by non-stationarity and are scale dependent.

4. Soil Loss Estimation Based on the USLE/GIS Approach Through Small Catchments - A Minor Field Study in Tunisia
University essay from Lunds universitet/Avdelningen för Teknisk vattenresursläraAbstract : A USLE/GIS approach was applied to estimate soil loss for the two catchments ‘Mrichet’ and ‘Sadine2’ in the semi-arid Tunisian Dorsal. The approach is inspired by the doctoral thesis ‘Water erosion modeling using fractal rainfall disaggregation – A study in semiarid Tunisia’ by Dr. Sihem Jebari. READ MORE
