(1), which relies on both the number of venous ostia and drainage patterns.
Assessments of drainage pattern and morphometric analysis provide information about the hydrological condition and nature of the outcrops within the watershed.
The goal of the proposed method is to use an unsupervised classification approach (SOM) to select objects in two different drainage patterns (dendritic pattern and modified basic pattern composed of mostly trellis and partially rectangular), which should be present in the target scale.
Qualitatively, the common types of drainage patterns along the basement highland are coarse dendritic to subdendritic parallel to subparallel and radial drainage and less common types are trellis.
The result of the drainage pattern map using automatic extraction technique is shown in Figure 11.
The usefulness of this operation is to clarify the relation of linear features (lineaments) with drainage pattern of study area and classify lineaments according to its relation with drainage pattern.
Worcester based its estimates on traditional end-of-pipe engineering solutions, or "grey infrastructure"; the Charles River numbers are based on more effective, cost-efficient techniques, which can be seen as "green infrastructure." This includes Smart Growth planning to prevent pollution in the first place, minimizing pavement and expensive pipes by using Low Impact Development techniques such as porous pavement, green roofs and rain gardens to recharge groundwater and mimic a more natural drainage pattern.
Soil auger observations made on a 50-m grid in selected window areas (Blocks A, B, and C) reveal that the relatively simple soil drainage pattern represented on the 1:25 000 scale map (Fig.
