How to Solve Topographical Maps (PART I) * Radial Drainage *presence of a volcano or conical mountain or hill Symbols and their Importance: * Dense Forest * Heavy rainfall * Disappearing stream: *Area of inland drainage – a pattern of streams that drain towards the center of a basin instead of towards the sea * Dry conditions; sandy soil * Underground streams (limestone areas) * Unsuitable for agriculture * Broken ground *occupation – lumbering * Open Jungle * Moderate rainfall * Scrubs * High temperature * Very low and scanty rainfall, especially if the vegetation is scattered * Ravines, badlands Scrubs and stony waste *lack of vegetation * Mining * Extensive erosion * Desert conditions * Seasonal flooding of rivers * Poor soil * Alternate wet and dry periods * grazing of domestic animals * Gulley erosion due to sudden heavy rainfall * Soft soil (which is good for agriculture) and silt * Dendritic Drainage Open scrub with scattered trees * Occupation – sheep/goat rearing; animal rearing * Less rain * Scattered/Less Vegetation * Rocks with uniform structure * Low lying areas/plains * Suitable for agriculture * Suitable for agriculture * Trellised Drainage * Bands of rocks varying in resistance * Hillside showing lack of vegetation * Land cleared for terrace cultivation * Alternate bands of hard and soft rocks * Chalk country – porous rocks and saturated during heavy rains * Not suitable for agriculture * Deciduous Forest * High ground * Green vegetation and brown contours * Highland * Water Points (ex: river banks, tanks, wells, etc.) * Unsuitable for agriculture * Low rainfall * grazing of animals * Low ground water table * Occupation – forestry * Tops of steep plateaus may be used for cultivation * Settlement on high ground/hill tops * For defense/protection * To avoid floods * Meandering River * Flat gradient due to reduced gravity and velocity * Suitable for agriculture * Causeway * Scanty rain * Dry stream * River in its middle course * Metalled Road * Perennial Wells * developed region *high water table With canals and tanks * Intensive use of land for agriculture * Brick kiln * Brick making * Lime kiln * Occupations – quarrying, mining * Perennial Rivers/Streams * Occupation – fishing * Non – perennial Rivers/Seasonal Rivers * Arid regions * Seasonal rainfall * Chalk country * Unmetalled Road * Undeveloped region * Footpath * Very steep regions * Railway line with station (RS) * Area of human settlement * Tidal Rivers * Near coasts * Dry River Bed * Semi-arid region * Seasonal rainfall * Perennial Tank * Rocky/hilly terrain * Tube Well * Intensive use of land for agriculture * Depression (Dep) * Arid region * On top of mounds/dunes * Dam * Sand Dunes * To control floods * Arid/desert conditions * Irrigation * Hydroelectricity * Kilns, Mines, Quarries * Human activity/occupation * Palm Trees * Settlements * Desert and coastal soil * Form Lines * Bamboos * Moderate to scanty rainfall * Swamp * Uneven ground OR * Sand dunes being leveled for agricultural purposes * Coastal region * High water table * Yellow Color Wash * cultivated area * Rock Outcrop * Occupation – agriculture * Scanty, desert-type vegetation * White Color Wash * Nucleated Settlement * Uncultivated land * Fertile plain/valley * Productive land * Cart tracks (motorable in dry season) * Seasonal rainfall * Dispersed Settlement * Large farms * Sparse population OR * Highland areas * Occupation – livestock rearing * Linear Settlement * Near valleys/coasts
