The location of the city at the junction of two major rivers also meant that it was at the junction of many major trade routes in Poland. Receiving goods and trading the food grown in the surrounding area led Sandomierz to accumulate great wealth, eventually paving the way for the Polish crown to settle there.
Most of the challenges in this area involve flooding or the climate. Flooding happens yearly because of the two large rivers that intersect in the city. While these floods rarely impact the city itself at the top of the hill, it can hurt the local farmers and food suppliers in the region. The climate contributes to this flooding with significant rainfall in the summer months, when many farmers try to harvest crops.
People adapted to this environment by recognizing what could be used as an advantage. Over time, effective flood maps were drawn, making farming in the region much easier. Other adaptations involved using the region's rains to their advantage by growing crops that need more water in the summer months to thrive. Due to these adaptations, the city was able to survive many harsh years before modern technology to become one of the largest historical sites in Poland.
