    Sammanfattning : The objective of this study was to assess the rainwater infiltration process in the unsaturated zone in an alluvial plain. Particularly, this study is focused on the Chocaya basin in central Bolivia. LÄS MER

  3. 2. Hydrogeological assessment of springs and groundwater in Carrizal, Costa Rica

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologi

    Författare :Markus Beckman; Jacob Sannum; [2020]
    Nyckelord :Hydrogeology; volcanic aquifer; Water balance analysis; MBR; Costa Rica; double ring infiltrometer; spring characteristics; minor field study.; Technology and Engineering;

    Sammanfattning : The main purpose of this thesis is to increase the understanding of how hydrogeological conditions are affecting the local water resources in Carrizal on the Barva Volcano, Costa Rica. Hydrogeological investigations of spring characteristics, soil infiltration rates and water flow in springs and rivers were conducted at the study area in Costa Rica as part of a Minor Field Study (MFS).

  4. 3. Infiltrationskapacitet för grönytor vid skyfall - Infiltrationsförsök och modellering i MIKE 21

    Master-uppsats, KTH/Mark- och vattenteknik

    Författare :Eva Melin; [2017]
    Nyckelord :Extreme rainfall; infiltration capacity; green areas; pluvial flooding; MIKE 21; Skyfall; infiltrationskapacitet; grönytor; pluviala översvämningar; MIKE 21;

    Sammanfattning : I världen idag pågår en urbanisering, vilket innebär att fler människor flyttar in till städerna. Det innebär att fler bostäder måste byggas för att uppfylla de nya behoven, och detta görs ofta genom förtätning av redan exploaterade områden. Vid förtätning av bostadsområden ökar ofta andelen hårdgjorda ytor. LÄS MER

  5. 4. Soil organic carbon and infiltrability in relation to distance from trees (Vitellaria paradoxa) with and without termite mounds in a parkland of central Burkina Faso

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Forest Ecology and Management

    Författare :Klara Hedemyr Joelsson; [2012]
    Nyckelord :Burkina Faso; parkland; agroforestry; trees ; Vitellaria paradoxa; termites; steady-state infiltrability; double-ring infiltrometer; bulk density; carbon content; macro-porosity;

    Sammanfattning : In semi-arid Burkina Faso access to water is crucial for crop-growth. Most common cropping system in the region is parklands, where crops are grown in association with trees. LÄS MER

  7. 5. Water infiltration in the Nyando River basin, Kenya

    Magister-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Aida Bargues Tobella; [2009]
    Nyckelord :Lake Victoria basin; Nyando River basin; steady-state infiltrability; bulk density; erosion; gully; runoff; sediment generation rate; double-ring infiltrometer; rainfall simulator; trees; vegetation cover; agroforestry;

    Sammanfattning : On-site and off-site effects of erosion in the Lake Victoria basin are some of the main contributors to the actual situation of poverty which is facing its population, one of the densest in the world. The Nyando River Basin (Western-Kenya) was identified as a regional erosion hotspot and one of the main sources of sediment and phosphorous into the Lake Victoria (ICRAF, 2001). LÄS MER
