1. 1. Water supply in hard rock coastal regions : The effect of heterogeneity and kinematic porosity

   Författare :Robert Earon; Bo Olofsson; Gerhard Barmen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coastal aquifer; Crystalline rock; Water balance; Geographic information systems; Water supply planning;

   Sammanfattning : Water resources in hard rock terrain are difficult to characterize due to heterogeneity and anisotropy in the fracture network, low porosities and limited recharge volumes available during the summer season. Three methods were developed and evaluated in order to assist in water supply planning. LÄS MER

3. 2. Form and Function of Coastal Areas

   Författare :Dan Lindgren; Andreas Bryhn; Lars Håkanson; Lars Brydsten; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coastal areas; morphometry; geographic information systems; GIS; ecological value; wave exposure; sediment; bottom dynamic conditions; mass balance modeling; Other earth sciences; Övrig geovetenskap; Earth Science with specialization in Environmental Analysis; Geovetenskap med inriktning mot miljöanalys;

   Sammanfattning : Coastal waters have high biological productivity and provide goods and services with a high monetary value. Coasts are used by many different stakeholders and are often densely populated. LÄS MER

4. 3. Swedish seagrass ecosystems in a changing climate : Coastal connectivity and global change sensitivity

   Författare :Diana Perry; Martin Gullström; Jason Hall-Spencer; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coastal seascape; shallow-water ecosystems; fish assemblages; connectivity; global change; climate change; multiple stressors; seagrass; Zostera marina; temperate region; Marine Ecology; marin ekologi;

   Sammanfattning : Coastal shallow-water ecosystems are essential for providing several goods and services globally, with seagrasses as an important contributor for maintaining high biodiversity and productivity within the nearshore seascape. The temperate species Zostera marina serves as a vital habitat for many species, including ecologically and economically important juvenile fish. LÄS MER

5. 4. Groundwater resources in hard rock coastal terrains : Insights into heterogeneity and spatial variability

   Författare :Robert Earon; Bo Olofsson; Okke Batelaan; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Crystalline Rock; Groundwater Balance; Kinematic porosity; Groundwater Recharge; Water Security; Coastal Aquifer; Land and Water Resources Engineering; Mark- och vattenteknik;

   Sammanfattning : Challenges regarding water security in hard rock coastal regions with limited soil cover are: a seasonal absence of recharge during times of peak residency, heterogeneity and variability of the fracture network, close proximity to saline water sources and spatially inconsistent storage and extraction. In areas where it is not feasible to connect residents to municipal water systems, a better understanding of the resilience of reservoirs is needed. LÄS MER

7. 5. Fish in the coastal seascape : exploring ecological processes and connectivity for conservation of temperate fish communities

   Författare :Thomas Staveley; Martin Gullström; Mats Björk; Regina Lindborg; Emma Jackson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; seascape ecology; landscape ecology; seagrass; marine habitats; fish; spatial analysis; connectivity; conservation; Sweden; temperate; Marine Ecology; marin ekologi;

   Sammanfattning : The need to understand patterns and processes in the marine environment has never been so profound as today, particularly as anthropogenic pressures upon coastal regions are drastically affecting habitats and species across a vast range. One approach to further understand these patterns and processes is through the use of seascape ecology methods. LÄS MER
