They then focused on the small wedges of coastal land, sandwiched between river drainages, where groundwater drains directly into the fragile ecosystems near shore.
If re-drainage is not indicated (drains are well positioned in the fluid cavity), clinically unsuccessful or impossible, the patient will proceed to step 2. The cystogastrostomy is dilated up to 18 mm and the cavity is entered with a therapeutic gastroscope to perform necrosectomy under direct endoscopic vision (see Figure 1).
The island is build-up of five geomorphic units that have different age (from >5000 to 325 y BP), vegetation (restinga ecosystems), soil hydrology (flat units or units with ridges and swales) and drainage (poorly drained, well-drained, and improved drainage).
Three sites contain storm-drainage outlets (drain 16 52 acres) that deliver effluent into the intertidal zone whereas five sites were located ⩾ 100 m away and served as comparisons to determine differences related to the presence of storm-water.
A factorial combination of 15 genotypes by two drainage conditions (drained or waterlogged) was established in a four-replicate randomized complete block.
A factorial combination of 15 genotypes by two drainage conditions (drained or waterlogged) was established in a six-replicate randomized complete block.
Rodent infestations predominantly affect the urban poor because conditions in poor communities promote rodent breeding, such as poor sanitation and drainage, open drains, uncollected solid waste, improper storage of food and overcrowding of homes [ 1, 2].
The tableland is cut by the drainage basins, which drains to north.
The dendritic type of drainage pattern is draining the Sarabanga watershed, which indicates that lithology and gentle slope category is controlling the study area.
Ensuing headcut erosion of countless tributaries has induced drainage network extension, draining large areas of the swamp and lowering the groundwater levels.
