  2. More urbanized communities had less power to assign non-farmersto the maintenance of canals;
  3. Urbanized or depopulated communities were characterized byhaving difficulty in maintaining the canals whereas the communities in the middle elevatedlocations succeeded in keeping up their maintenance;
